You are right that having a larger diameter makes the tube stiffer with the same amount of materials. That is one of the reasons why aluminium frames had rather fat tubes.
In fairness to Lexon, all titanium 24mm spindles had this design (flaw) because the milling of the inside of a tube is rather costly compared to the outside milling. (Guessing that the Elilee crank has been milled on the inside)

Weight comparison:
R8100 170mm cranks, no power meter: 555gr
Xcadey 172.5mm cranks with power meter: 592gr
Lexon 167.5mm with Xcadey power meter: 462gr

tried installing the crank yesterday and had mixed experience...

1. the power-meter installation went smooth thanks to the help of the LBS that had right lock ring tool (used for bottom brackets as well)
2. mounting the axel into the left crank arm, no problems. good fit and some wired white paste was already available. still added some grease for good measures
3. mounting the cranks to frame: well this was not going too smooth....
- no spacers where included --> used the spacers from
- the adjustment ring from the left crank arm has an inner diameter of 29mm, this is too big for the spacers which are 28mm OD...
hence all spacers must go on the right side, which is not good for symmetry and might increase the flex (if there is any with my spider legs) ass the right side sticks out more
- the adjustment ring has also a rather short rang compared to the older XCADEY version
- added both spacers on the right side and still have larger gap even with the adjustment ring fully out...
==> not really that well ridable
Now I ordered some more 24mm spacers from Amazon, should arrive today and use this temporarily.
My idea is to use an aluminum head-set spacer (ID 28.6mm, OD33.5mm) to put it on a 24mm crank spacer (OD 28.7mm) via hot/cold shrink or sandpaper followed by GLUE. does anybody has experience with it?

Pics from the spacer and the alignment ring.
It seems that the Elilee X310 24mm has a better ring that goes close to the 24mm axle

Maybe just get rid od the ring and put spacers there. I've done that on my dub cranks in my gravel build, no problem.

Managed to mount the crankset!
Figured that the right side needed much more spacers to create clearance between the lockring and the bottom bracket outer shell.
Once this was done the adjustment ring on the left was sufficient to close the gap and avoid play. The ring sits barely on the inner BB seal, which should be fine.
Lexon staff agreed to put spacers in future deliveries. Some installation instructions would be helpful as well....
Below the new and the old cranks on my Sculptura 9000.
Haven't rode it yet but should be happening later this week.

Anyone used the carbon chainrings that come with the lexon R1 "purple" version?
Wondering about how they handle, flex, durability etc. I much prefer the carbon weave look over the non-purple version.

Got the powermeter now as well, no problem with mounting it, in the end 60 gram more than the spider, so I'm quite content.

So far so good, have done 10 rides ISH and going for a bigger 160km round today, Onyu pass in Japan.
The cranks are holding up very well only the Powermeter was/is a bit off compared to me wahoo kickr. Like 30 watts, which is not that insignificant as I'm not enjoying Pogi's power output

Yeah that's why I don't want any of those elille, cybrei, lexon cransets as the all use those xcadey power meter. It a shame magene don't make spider PM for easton standard.

Can always get sram red crankset and funny enough it's cheaper then those Chinese ones lol. But it is dub and I am afraid of putting a dub into pf bottom bracket as everyone says it's just too much compromise with bearings size.

You can adjuat the scale on xcadey

You can also get a sigeyi for easton which are better calibrated

I've been comparing the Wahoo Kickr and Xcadey power-meter and changed the scale to 105% but I do miss the offset function as well.
Another potential point of improvement for the Xcadey is that the APP does not show the latest adjusted scale value...

The Sigeyi was more than US$100 more expensive, which I felt a bit much for a power-meter that cost US$250 with the Xcadey brand.

If I read this correctly, the Xcadey was reading low for you? Since you had to scale it up to 105% ?

I should probably do some specific testing against my indoor trainer (Elite Suito). But at the moment, it feels accurate, or even reading a bit higher than my trainer. But I always just assumed this is due to drivetrain losses (point of measurement). And the fact that riding indoors just feels harder.

Lets get back to talking about the cranks guys, not power meters
